GLOVE OR DRESSFASTlENER.

SPECIFICATION formingpart of Letters Patent No. 685,397, dated October29, 1901.

Application filed June 10,1901. Serial No. 63,831. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL B. DONCHIAN,

I a citizen of the United States, and a resident of Hartford, in thecounty of Hartford and used for the purpose of temporarily uniting themeeting or overlapping edges of articles of apparel, as a dress-skirtand a waist, or for securing in like manner the meeting parts of aglove.

Theobject of my invention is to provide a fastening device of this classfor general use and one in which the two separable members will resistany force thrown upon the two parts and tending to disengage them,except such force or strain be exerted substantially in the line of theaxis of the fastening.

Referring to the drawings which form part hereof, Figure 1 is a planview of the working face of one of the fastener members. Fig. 2 is aplan view of the working face of the complementaryfastener member- Fig.3 is a side View of the fastener as attached to two separate parts of agarment and united. Fig. 4= is a detail View, in central section, of thefastener on enlarged scale and illustrating the construction. I

In the accompanying drawings the letter a denotes the fastener as awhole, which is composed of two main parts or members I) and c, adaptedto be attached, respectively, to the parts d and e of a garment, of anarti cle of apparel, or other parts to be detachably fastened together.Each of these fastener members It and c is provided on the adjacentsurfaces with projections which interengage and hold each other with ayielding grasp. Broadly stated, such features in a two-part fastener arenot new; but a serious defect in those prior to my invention has beenthe ease with which a strain on the fastener parts in a plane at but aslight angle to the surface of the base tilts and unfastens the device.My invention obviates this defect.

On one of the fastener members 5 there is a projection f, which ispreferably bulbous in shape and of less diameter at its. base than aboveit, thus providing a recess f into which the outer edge of a socket partg, the walls of which project from the opposite fastener member, mayfit. The projection fis compressible to a degree, being made sopreferably by the slits f, which enter for almost half the depth of theprojection, which is made of a resilient material. The walls .of thesocket part g' are high enough to fit over the projectionf, and the edgeg is inturned, so as to fit snugly into the recess f the body part ofthe spring memberf yielding inward to permit this edge' g" to pass overit.

On the fastener member which supports the projectionf(the spring member)there is 1 an annular guard h, secured to the base of the part, and thisguard embraces the annular projection g on the socket member. of thefastener and prevents the disengagement of the two fastener members byany strain except in the direction of the axis of the fas-' tenerthatis, in a line normal to the plane of the base of the fastener. Thisguard has the edge h slightly inturned and is of a diameter to closelyembrace the wall of the socket, at the bottom of which a recess g islocated. This edge It springs into the recess 9 and holds its place witha yielding grasp.

From an examination of Fig. 4 of the drawings itwill be seen that whenthe socket member c and the spring memberf of the fastener are engagedthe edge g of the wall of the socket part is located in the recess f atthe base of the projection, and the edge h of the guard h'lies in therecess 9' at the base of the wall of the socket part. The guard solocated opposes any force applied to the parts which would tend to tiltthem out of engagement,as no compressing strain is thrown upon thespring member.

As soon as any force acts in a direction nor mal to the base of thefastener parts the parts are readily disengaged. by the action of theedge 9' of the wall of the socket part c, which slides along the surfaceof the spring projection and compresses it to a degree sufficient topermit the disengagement of the parts.

Any suitable means may be provided for securing the two parts of thefastener to the article or to the parts to be fastened by it. Holes maybe made in the base of each of the members of the fastener, throughwhich a thread may pass, so that the fastener may be held in place bysewing, or other obvious means may be employed.

The fastener members may be made of any convenient material and size andof as many parts in each part as desired, the main feato re of myinvention being the guard device, so located as to prevent the tiltingof the two fastener members on each other and to so meet the strainstending to such result by what are practically rigid braces.

In the preferred form ofthe device,as shown in Fig. 4 of the drawings,there is an opening through the socket member 0, and the springprojectionfextends to some extent beyond the plane of the base of thesocket member. This is a convenient form for some uses and is ofadvantage in enabling pressure to be applied to the projecting portionfrom the rear of the socket member for disengaging the two fastenermembers; but this feature is not essential to my invention.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. In combination in a fastener, a socket member having an annularprojection and means for engaging a projection on the complementaryspring member, a spring member bearing a compressible projecting partand means for engaging the annular projection on the socket member, andan annular guard located on the spring membersaid guard having a wallsurrounding and engaging the annular projection on the opposite member.

2. In combination in a fastener, a socket member having an annularprojection with the outer edge inturned andhaving a groove or recess atthe base of the projection, a spring member bearing a compressibleprojecting part having a recess at its base, and an annular guard whichembraces the annular projection on the opposite body part and has itsedge provided with an inturned pro-' jection adapted to fit into thegroove or recess in the wall of the socket part.

3. In combination in a fastener, a socket member having an openingthrough its base and an annular projection, a spring member having acompressible projection extending beyond the base of the socket memberwhen the parts are engaged, means for removably holding the springprojection in the annular projection, and a guard located on the springmember, said guard having a wall surrounding and engaging the annularprojection on the opposite member.
